Optech Snoot Boots are cylindrical neoprene lens pouches which can be used either as a lens or tripod head cover, or cinched closed for full protection against dust, moisture and impact. The cylindrical design and wide-mouth opening makes it quick and easy to get the lens in and out, and 'Wide Body' versions are availablle for super-wide zooms, or as push-on covers for large telephoto lenses.
